Disable gc logs from mixer istio-telemetry pods

Hello.

I have a plethora of garbage collection logs emitted to stderr from istio-telemetry pods – for example:

gc 1748368 @4319896.596s 0%: 0.017+8.3+0.011 ms clock, 0.10+2.2/9.1/24+0.066 ms cpu, 27->28->14 MB, 28 MB goal, 6 P

Helm settings look like this:

# Common settings used among istio subcharts.
global:
...
  # Comma-separated minimum per-scope logging level of messages to output, in the form of <scope>:<level>,<scope>:<level>
  # The control plane has different scopes depending on component, but can configure default log level across all components
  # If empty, default scope and level will be used as configured in code
  logging:
    level: "default:error"

Is there a way to disable this behavior? My logging budget will thank you.
